On the six reasons why LED light source becomes the projection savior

The inventions of the 20th century were the most invented, and even one of the greatest inventions of the 20th century was not an exaggeration. Compared to oil lamps and incandescent lamps, LED light sources are called third-generation light sources. What are the advantages of LED light sources? Is the projector using LED technology ?

LED light source

LED technology is used in a wide range of applications, most often with LED projectors, LED TVs and LED displays. Specifically, it should be called LED light source projector, LED backlit TV and LED backlit display.

At this stage, LED technology can be applied in almost all fields: a, LED display technology - LED splicing wall; b, LED backlight application - LED projector, LED-backlit flat-panel TV; c, LED lighting application - LED lighting , LED flashlights, LED car taillights; d, LED decorative applications - LED decorative lights; e, LED signal lights, this is almost all traces of electrical equipment. The projector of the traditional light source can meet the needs of most users in terms of brightness. However, the short-lived ultra-high pressure mercury design allows the home users to abandon the projection of the flat-panel TV. The toxic and harmful mercury is a hatred of environmentalists. The expensive late bulb investment is very inconsistent with the consumption habits of the Chinese people, which makes the SMEs feel a lot of pressure. Compared with the booming landscape of LED technology, LED projections seem to be incapable.

Due to various ills, in the face of the increasingly expanding projection demand market, the projector of the traditional light source has been slightly tired, then can LED become a savior? With the release of Texas Instruments' miniature HD DLP chip, HD micro-investment has become the future development trend, with a resolution of 500 lumens of 1280×800, which suddenly rekindled our enthusiasm for LED light source applications.
